In promiscuous mode, the NIC allows all frames through, so even frames intended for other machines or network devices can be read. But, in non-promiscuous mode, when the NIC receives a frame, it drops it unless it is addressed to its specific media access control address or is a broadcast or multicast addressed frame.
